DRILL

A Practical Comparison of Finite Element and Boundary Element Formulations for Modeling Sound Radiaods (like finite element (FE) methods) require an appropriate treatment of the radiation condition, involve usually a larger amount of data (as implied by the related volume mesh) but are characterized by sparse matrices and reduced calculation times.

Transient Analysis of Wave Propagation in Unbounded Media: Space-Time Methods and Continued-Fractio these boundary conditions have been proposed by various researchers in the last two decades (for a survey, see [Givoli, 1992]). Some are local in both space and time. Others are global in space, time, or both. Local methods have case-specific performance, but are economical, whereas, global methods are accurate but expensive.
